VULGANIZER.

Specification of Letters Patent.

Application filed June 21, 1912. Serial N 0. 705,063.

To all '10 hom it may concern:

Be it known that I, CHARLES TAARUD, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of hfinnesota, have invented new and useful Improvements in Vulcanizers, of which the following is a specification.

This invention relates to vulcanizers and the object of the invention is to provide a simple and efficient device by which patches may be vulcanized on inner tubes of automobile or other tires and which may be conveniently carried around in a repair kit.

A further object of the invention is to provide a vulcanizing apparatus which will avoid some of the difliculties encountered in other vulcanizers of spreading the blow out hole or puncture, enlarging thetube at that point, and also making a thick edge on the patch. This invention is designed to obviate these difiiculties and to produce a patch which will be thick and strong in the center and which will taper to a thin edge or at its juncture with the tube.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in whic j Figure 1 is a side elevation with the tube in section arranged between the parts. Fig. 2 is a top plan view. Fig. 3 is a perspective view of the bottom plate. Fig. 4 is a sectional view of the invention showing a tube therein to be vulcanized. I

In the specific embodiment of the invention, as illustrated herein, the device consists in a fuel retaining member 1 and a clamping member 2. The former or fuel retaining member comprises a bottom plate 3 whichis substantially flat and preferably oval-shaped, as shown, so as to adapt the a device along blow outs in the tube. Integral with the bottom plate is the side flange 4 which curves inwardly at the-upper end so. as to constrict the flame and to throw the heat toward the center of the device. Also integral with the device and projecting upwardly from the bottom are a plurality of radiating arms 5 which form compartments 6, all of which are communicated. These arms willbe known hereafter as the spider and are provided in order to conduct the heat to the base plate 3. The member 2 comprises an oval. plate which has mounted thereon a felt equalizing pad 7 and is'provided with a pair of ears extending from opposite sides of the plate and carrying bolts 9 adapted to removably connect with the ears 10 on the fuel holder 1. These ears 10 are slotted, as shown at 11, to receive the bolts and the bolts carry wing nuts 12, by which the arts may be clamped together upon the tu e, as shown in Figs. 1 and 4.

In the operation of the device, the patch is properly applied to the tube and the tube clamped in between the members 1 and 2.

The fuel retainer 3 is then filled with gasolene, or other similar fuel, which flows into all of the compartments 6 and this fuel ignited. When all of the fuel burns out of the burner, the vulcanization will be completed. The pad 7 is provided so that the patch will bed itself into the same. If this pad were not" used, the gum in flowing just before it cures, would be pressed into the hole in the tube and would spread the same, thus enlarging the tube at that, point and also making a thick edge on the patch.

What is claimed is In a vulcanizer, a base member, a hollow upper'member having an opening in its upper portion and adapted to fit over said base member and having its wall inwardly converging toward said opening, the edge of the wall surrounding said opening overhanging the base portion of said up er member.
